Divided bass pickup for BOSS guitar synthesizer products with the Serial GK interface.

The BOSS GK-5B Divided Pickup is a specialized bass pickup designed for the GM-800 and other BOSS guitar synthesizer products. Unlike standard guitar pickups—which send all string signals to a combined output—the GK-5B senses each string individually, sending their signals to separate outputs within the Serial GK system. This isolated string information allows your compatible BOSS product to perform all sorts of advanced processing feats not possible with standard pickups.
